lNCAND ESCENT-LAMP SOCKET.

SPECIFICATION forming part of Letters Patent No. 738,648, datedSeptember s, 1903.

Application filed June 12, 1903.

T Iall whom it may concern:

Be it known that we, JOSEPH L.-Y0s'rand OWEN E. *KENNEY, citizens of theUnited States, residing at Toledo, in the county of Lucas and State ofOhio, have invented certain new anduseful Improvements in-Incandescent-Lamp Sockets; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as willenableothers skilled inthe art to which it appertains to nake'and.usethe same.

Our invention relates to certain new and useful improvements inincandescent-lamp sockets, and more particularly tothat class in whichthe switch mechanism and contacts are located within a porcelain orothersuitable insulating-body.

Ourinvention has forits object simplicity and economy ofconstruction,strength and durability of the several parts, and facilityin the assembling of the same.

With these ends in View our invention consists in the details ofconstructionand ar- "line y y of Fig. 1.

rangement hereinafter more particularly described and claimed.

In order that those skilled in the art to which our invention appertainsmay know how to make the same and fully appreciate its advantages,wewill proceed to describe ourimand its bearings removed from theinsulator block or barrel.

Similar reference-numerals indicate like parts in the several figures ofthe drawings.

1 represents "a block or barrel,'of porcelain or other suitableinsulating material, formed with a diametric recess or chamber 2, withinthe outer end of whichlis located one of the circuit-wire posts 3. Aperipheral recess or chamber-4 is formed to receive asecond circuit-wirepost-t5, and the posts 3 and 5 are secured in position by suitablescrews 6 passing through the bottom of the block or barrel 1 andthreadedinto the posts.

Within one side of the block or barrel 1 and Serial No. 161,130. (Nomodel.)

. at right angles to the recess or chamber 2 is .formed a gateway orpassage 7, with oppositely-disposed vertical shoulders 8, and at thelower extremity of this gateway or passage is ashort vertical wall 9.(See Fig. 1.) A vertical channel 10 is formed in the body of the blockor barrel for the reception of the end of the spindle of the key 11.

Within the diametric chamber or recess 2 is located the conductor-plate12 and the switch 13, such as shown and described in a concurrentapplication filed by us and bearing Serial No. 161,128.

The key 10 is mounted in bearings near the are connected by a singleclamping-screw 15 near the upper ends. The lower. ends of the plates 14'are preferably curved to coincide with the similar shape of the lowerextremity of the gateway or passage 7 and are of such width as to fitwithin the said gateway and against the vertical shoulders 8 and theshort vertical wall 9, as clearly shown at Figs. 1 and 3, and to beclamped in position by the screw 15 in an obvious manner. The key 11 hasits spindle 16 passed through the holes or bearings near the lower endsof the plates 14, and the switch-operating cam or block 17 is thenlocated upon the spindle, the extreme end of which is housed within thevertical recess 10 in the block or barrel 1, as best shown at Fig. 1,and when the plates 14 are clamped against the shoulders 8 and the wall9 it will be readily understood that the key 11 and its cam or block 17are rigidly held in proper operative relation with the switch 13. A capor closure 18 of insulating material, is secured to the upper ends ofthe circuitwire posts 3 and 5 by screws 19 and conceals and protects theswitch mechanism, as clearly shown. r h

From the construction shown and described it will be readily seen thatthe block or barrel 1 is simple and economic of construction and thatthe same is strong and durable and that as it contains all the recessesand cham bersfor the several metallic devices, conductors, &c., and asthe closure or cap is a simple flat disk or cover no special adjustmentbetween the cap 18 and the block or barrel 1 is rendered necessary, aswould be the case where the barrel is composed of two blocks each havingcorresponding recesses or cham-.

obvious, metal bearings, and hence are more accurate and reliable thanwould be the case if such bearings were formed in the insulatingmaterial.

We of course do not wish to be confined to any exact design orproportions of the several'parts of our improved socket, as they may bevaried without departing from the spirit of our invention, which residesin the generic idea of providing seats and receptacles or chambers forthe various metallic devices within a single block or body of insulatingmaterial and confining and concealing the same by a simple cap orclosure and also in mounting the switch-operating key rotatively withinmetallic bearings independent of the insulator block or barrel andremovably securing thesame in proper position by clamping the saidbearings against suitable shoulders formed upon the insulator block orbarrel. 7

It will be understoodthat although we have not shown the same ourimproved socket is designed to be secured within the ordinarysheet-metal shell and base in the usual manner.

Having described the construction and advantages of our improved socket,what we claim as new, and desire to secure by Letters Patent, is-

1. In an incandescent-lamp socket, an insulator block or barrel providedwith a diametric vertical recess or chamber adapted to receive switchmechanism and one of the circuit-wire-post plates and'with a radialrecess adapted to receive one end of the other circuit-wire-post plate;a non-recessed cap or cover composed of insulating material, andcircuit-wire-post plates secured at their opposite ends to the insulatorblock or barrel and the cap or cover to hold the block or barrel and thecap or cover in close relation, substantially as set forth.

2. In an incandescent-lamp socket,a switch containing insulator block orbarrel formed with suitable diametric and radial recesses or .chambersadapted to receive the switch devices and the circuit-wire posts, andhaving a passage or opening transverse to the switchcontaining recess orchamber formed with abutments or shoulders, in combination with aswitch-key rotatively mounted in metallic bearing-plates clamped inposition against the abutments or shoulders of the open passage-way,substantially as and for the purpose set forth.

3. In an incandescent-lamp socket such as described and having aninsulator block or barrel with a switch-mechanism-containing .recess orchamber and a vertical wall adjacent to the switch-containing recess orchamber, a switch-key rotatively mounted in metallic bearing-plates adjustably connected by a screw and adapted to be clamped in properposition upon the vertical wall of the insulator block or barrel, as setforth.

4. In an incandescent-lamp socket such as described, the switch-keymounted in parallel bearing-plates secured together by anadjusting-screw and adapted to be secured to the switch-containinginsulator block or barrel or removed therefrom by the adjustment of theconnecting-screw as hereinbefore set forth.

- In testimony whereof we affix our signatures in presence of twowitnesses.
